[0013] The wall mounting device 1 is a device for mounting any wall embedding object (not shown) to be embedded in a wall (or a ceiling) to an opening 101 of a wall material 100 (see FIG. 1). Examples of wall embedding objects include a wall embedding wireless LAN (Local Area Network) router, a wall embedding intercom, a wall embedding outlet, a wall embedding gas supply device, a wall embedding emergency light, and a ceiling embedding air conditioner, and the wall embedding device can be used to contribute to miniaturization. The wall mounting device 1 has a spring mechanism including shafts 21-24, stopper members 31 and 32, pressure plates 40 and 50, and compression springs 61-64. The wall mounting device 1 includes a front plate 10, shafts 21-24, stopper members 31 and 32, pressure plates 40 and 50, and compression springs 61-64.

[0014] The front plate 10 is a plate-like plate that is disposed on the front surface 100a of the wall material 100 when the wall mounting device 1 is attached to the opening 101 (a rectangular opening in FIG. 1) of the wall material 100 (see FIG. 1). The front plate 10 has an open window 15 in the center for arranging an object to be embedded in the wall (not shown). The window 15 has recesses 15a, 15b for mounting the object to be embedded in the wall (not shown). The front plate 10 has holes 11-14 (e.g., screw holes, through holes, keyholes, etc.) for mounting the object to be embedded in the wall (not shown). The recesses 15a, 15b and the holes 11-14 may not be provided if they are not required. The front plate 10 can be configured to be rectangular when viewed from the front. A portion of the rear surface of the front plate 10 near the outer periphery abuts against the peripheral portion of the opening 101 in the front surface 100a of the wall material 100 (pressed against by the pressing force of the compression springs 61-64). A portion of the back surface of the front plate 10 near the window portion 15 is disposed so as to overlap the opening 101 when viewed from the front side. One ends of a plurality of shafts 21-24 (four in FIG. 1) arranged to extend in the front-rear direction are fixed to the portion of the back surface of the front plate 10 near the window portion 15 near the end face of the opening 101 of the wall material 100.

[0015] The shafts 21 to 24 are axial members (see FIG. 1). The shafts 21 to 24 are arranged to extend in the front-rear direction. One end of the shafts 21 to 24 is fixed to the rear surface of the front plate 10. The shafts 21 to 24 are arranged near the end surface of the opening 101 of the wall material 100 so as not to interfere with the wall material 100 when the wall mounting device 1 is inserted into the opening 101 of the wall material 100 (see FIG. 2). The shafts 21 to 24 are inserted into the opening 101 of the wall material 100. The other ends of the shafts 21 to 24 are fixed to corresponding stopper members 31 and 32. In FIG. 1, the stopper member 31 is fixed to the other ends of the shafts 21 and 22, and the stopper member 32 is fixed to the other ends of the shafts 23 and 24. Compression springs 61 to 64 are arranged on the outer periphery of the shafts 21 to 24. The shafts 21 to 24 are inserted into the slide holes 41, 42, 51, and 52 of the corresponding pressure plates 40 and 50 on the front plate 10 side of the compression springs 61 to 64. The shafts 21 and 22 inserted into the slide holes 41 and 42 of the pressure plate 40 are configured not to overlap with the shafts 23 and 24 inserted into the slide holes 51 and 52 of the pressure plate 50.

[0016] The stopper members 31 and 32 are members that lock (support) the other ends of the compression springs 61 to 64 arranged on the outer periphery of the shafts 21 to 24 (see FIG. 1). The stopper members 31 and 32 are fixed to the other ends of the corresponding shafts 21 to 24. In FIG. 1, the stopper member 31 is fixed to the other ends of the shafts 21 and 22, and the stopper member 32 is fixed to the other ends of the shafts 23 and 24. The stopper members 31 and 32 are arranged near the end faces of the opening 101 of the wall material 100 so as not to interfere with the wall material 100 when the wall mounting device 1 is inserted into the opening 101 of the wall material 100 (see FIG. 2). Although there are two stopper members 31 and 32 in FIG. 1, the other ends of the shafts 21 to 24 may be fixed to one stopper member. Further, in FIG. 1, the stopper members 31, 32 are configured to bridge the corresponding shafts 21 to 24, but they may be provided individually for each of the shafts 21 to 24 without bridging them, and they do not have to be in the form of a plate.

[0017] The pressure plates 40, 50 are members for pressing the periphery of the opening 101 in the rear surface 100b of the wall material 100 against the front plate 10 (see FIG. 1). There are a plurality of pressure plates 40, 50. The pressure plates 40, 50 each have a plurality of slide holes 41, 42, 51, 52 penetrating therethrough. The pressure plates 40, 50 are movable in the front-rear direction between the front plate 10 and the compression springs 61-64. The corresponding shafts 21-24 are inserted into the slide holes 41, 42, 51, 52. The slide holes 41, 42, 51, 52 are holes for sliding the pressure plates 40, 50 outward (both left and right outward in FIG. 1) relative to the shafts 21-24. The slide holes 41, 42, 51, 52 guide the movement of the pressure plates 40, 50 relative to the shafts 21-24. The guide direction of the slide holes 41, 42 of the pressure plate 40 is configured to be the opposite direction to the guide direction of the slide holes 51, 52 of the pressure plate 50. The slide holes 41, 42, 51, 52 are configured to guide the pressure plates 40, 50 from a state in which the peripheral portion of the opening 101 in the wall material 100 is not sandwiched between the front plate 10 and the pressure plates 40, 50 to a state in which the peripheral portion is sandwiched between the front plate 10 and the pressure plates 40, 50 by sliding the pressure plates 40, 50 in a first direction (which may be a left-right direction or a top-bottom direction in FIG. 1) relative to the shafts 21 to 24. In other words, the pressure plates 40, 50 are configured not to interfere with the wall material 100 when the wall mounting device 1 is inserted into the opening 101 of the wall material 100 (see FIG. 2) when closed inward (see FIG. 5(A)). The pressure plates 40, 50 are configured to come into contact with the periphery of the opening 101 on the back surface 100b of the wall material 100 when the wall mounting device 1 is inserted into the opening 101 of the wall material 100 and opened outward (see FIG. 5(B)). The slide holes 41, 42, 51, 52 have recesses 41a, 42a, 51a, 52a for inserting the shafts 21-24 from the radial direction.The recesses 41a, 42a, 51a, 52a are configured so that the shafts 21-24 are inserted by sliding the pressure plates 40, 50 in a second direction (a direction different from the first direction (e.g., a perpendicular direction); in FIG. 1, it may be the up-down direction or the left-right direction) when the peripheral portion of the opening 101 in the wall material 100 is sandwiched between the front plate 10 and the pressure plates 40, 50. In other words, the recess direction of the recesses 41a, 42a, 51a, 52a is set so as to be a direction different from the sliding direction for opening and closing the slide holes 41, 42, 51, 52 (a direction perpendicular to the first direction in FIG. 1). The recesses 41a, 42a, 51a, 52a are configured so that the shafts 21-24 are press-fitted or fitted into them. When the pressure plates 40, 50 are open outward, the shafts 21-24 corresponding to the recesses 41a, 42a, 51a, 52a are inserted (press-fitted, engaged) into the recesses 41a, 42a, 51a, 52a, thereby restricting the movement of the shafts 21-24 to prevent the pressure plates 40, 50 from closing and suppressing the inclination of the pressure plates 40, 50 relative to the back surface 100b of the wall material 100.

[0018] The compression springs 61-64 are elastic members that receive a compression load (see FIG. 1). The number of the compression springs 61-64 is the same as the number of the shafts 21-24. The compression springs 61-64 are arranged on the outer periphery of the corresponding shafts 21-24. The other ends of the compression springs 61-64 are restricted from moving toward the back (rear) by the corresponding stopper members 31, 32. One end of the compression springs 61-64 presses the corresponding pressure plate 40, 50 toward the front plate 10 when the wall material 100 is sandwiched between the front plate 10 and the pressure plates 40, 50. The compression springs 61-64 are compressed between the corresponding stopper members 31, 32 and the pressure plates 40, 50 when the wall material 100 is sandwiched between the front plate 10 and the pressure plates 40, 50.

[0019] The wall mounting device 1 having the above-mentioned configuration can be mounted to the opening 101 of the wall material 100 as follows.

[0020] 2, with the pressure plates 40 and 50 closed, the stopper members 31 and 32, shafts 21 to 24, compression springs 61 to 64, and pressure plates 40 and 50 of the wall mounting device 1 are inserted into the opening 101 from the front surface 100a side of the wall material 100, and the front plate 10 of the wall mounting device 1 is brought into contact with the front surface 100a of the wall material 100. This results in a state in which a part of the wall mounting device 1 protrudes from the rear surface 100b side of the wall material 100 as shown in FIGS.

[0021] Next, while pressing the pressure plates 40, 50 toward the stopper members 31, 32 so that the compression springs 61-64 compress them, the pressure plates 40, 50 are slid so that they open outward on both the left and right sides, as shown in Fig. 5(A) and Fig. 5(B). As a result, a portion of the pressure plates 40, 50 overlaps with the back surface 100b of the wall material 100 in the front-rear direction, and the pressure plates 40, 50 are pressed toward the front plate 10 by the compression springs 61-64, and the peripheral portion of the opening 101 in the wall material 100 is sandwiched between the front plate 10 and the pressure plates 40, 50.

[0022] Finally, the pressure plates 40, 50 are slid downward, and the shafts 21-24 are inserted (or pressed or fitted) into the recesses 41a, 42a, 51a, 52a of the pressure plates 40, 50 as shown in Figures 6 and 7. This restricts the left-right movement of the pressure plates 40, 50 and also suppresses the inclination of the pressure plates 40, 50 relative to the back surface 100b of the wall material 100, so that the pressure plates 40, 50 can be maintained in an open state, and the wall mounting device 1 can be fixed to the wall material 100.

[0023] According to form 1, the wall mounting device 1 can be fixed to the opening 101 of the wall material 100 by simply pressing and sliding the pressure plates 40, 50 of the wall mounting device 1, so that the work can be done even without tools or in a place with a narrow working space, which contributes to improving the workability of installing the device.

[0024] Furthermore, according to form 1, since there is no need to handle fasteners such as screws, rivets, etc., there is no need to worry about fasteners falling off, and the wall mounting device 1 can be attached to the wall material 100, improving workability.

[0025] Moreover, according to the first embodiment, no parts are required for the front plate 10 other than the shafts 21 to 24, the stopper members 31 and 32, and the compression springs 61 to 64, so that costs can be reduced.

[0026] Moreover, according to the first embodiment, there is no need to put one's hand into the rear surface 100b of the wall material 100, and the wall mounting device 1 can be easily attached.

[0027] Furthermore, according to form 1, the pressure plates 40, 50 are pushed out by the pressing force of the compression springs 61-64 in a compressed state, so that the pressure plates 40, 50 can have a large range of movement in the front-to-rear direction. This makes it possible to attach the wall mounting device 1 to the opening 101 of wall materials 100 of various thicknesses, thereby improving workability.

[0028] [Form 2] The wall mounting device according to the second embodiment will be described with reference to the drawings. Fig. 8 is a partially enlarged cross-sectional view showing a schematic state in which the second example of the wall mounting device according to the present disclosure is inserted into an opening in a wall material, the pressure plate is opened, and the shaft is inserted into the recess.

[0029] The second embodiment is a modification of the first embodiment, in which a sheet member 70 is disposed between the pressure plate 40 and one end of the compression spring 61 (see FIG. 8). A sheet member similar to the sheet member 70 in FIG. 8 is disposed at a location corresponding to between the pressure plate 40 and one end of the compression spring 62 in FIG. 1, between the pressure plate 50 and one end of the compression spring 63, and between the pressure plate 50 and one end of the compression spring 64. The sheet member 70 has a through hole 71 through which the shaft 21 is inserted. The sheet member 70 is preferably larger than the outer diameter of the compression spring 61. For example, a resin washer, a metal washer, a disc spring, or the like can be used as the sheet member 70. The sheet member 70 may be molded to match the shape of one end of the compression spring 61, or may be fixed (adhered, welded, fixed, or the like) to one end of the compression spring 61.

[0030] According to the second embodiment, like the first embodiment, it is possible to contribute to improving the workability of installing the device, and since the pressing force of the compression spring 61 is evenly transmitted to the portion of the pressure plate 40 around the shaft 21 via the sheet member 70, it is possible to suppress the inclination of the pressure plate 40 relative to the back surface 100b of the wall material 100.

[0031] [Form 3] The wall mounting device according to the third embodiment will be described with reference to the drawings. Fig. 9 is a schematic diagram showing the configuration of a third example of the wall mounting device according to the present disclosure, in which (A) is a partial cross-sectional view and (B) is a partial cross-sectional view taken along the line Y-Y' when the device is mounted on a wall material.

[0032] The wall mounting device 1 is a device for mounting any wall embedding object (not shown) to be embedded in a wall to an opening 101 of a wall material 100. The wall mounting device 1 includes a front plate 10, a shaft 21, a compression spring 61, a pressure plate 40, and a stopper member 31.

[0033] The front plate 10 is disposed on the front surface 100a of the wall material 100 and is configured to abut against the peripheral portion of the opening 101 in the wall material 100. The shaft 21 is configured to have one end fixed to the front plate 10 and extend in the front-rear direction to be inserted into the opening 101. The compression spring 61 is disposed on the outer periphery of the shaft 21. The pressure plate 40 has a slide hole 41 through which the shaft 21 is inserted and is configured to be movable in the front-rear direction between the front plate 10 and the compression spring 61. The stopper member 31 is fixed to the other end of the shaft 21 and configured to engage the other end of the compression spring 61. The slide hole 41 is configured to guide the peripheral portion of the opening 101 in the wall material 100 between the front plate 10 and the pressure plate 40 from a state in which the peripheral portion is not sandwiched to a state in which the peripheral portion is sandwiched between the front plate 10 and the pressure plate 40 by sliding the pressure plate 40 relative to the shaft 21 in a direction perpendicular to the front-rear direction. The compression spring 61 is configured to press the pressure plate 40 against the front plate 10 when the peripheral edge of the opening 101 in the wall material 100 is sandwiched between the front plate 10 and the pressure plate 40 .

[0034] According to form 3, the wall mounting device 1 can be fixed to the opening 101 of the wall material 100 by a simple pressing and sliding operation of the pressure plate 40 of the wall mounting device 1. This makes it possible to perform the work even without tools or in a place with a small working space, thereby contributing to improving the workability of installing the device.
